SAW.

SPECIFICATION forming part of Letters Patent No. 782,396, dated February 14, 1905.

Application filed August 4, 1904. Serial No. 219,480.

To all whom it may concern:

Be it known that I, Jnssn L.HIERS, a citizen of the United States, residing atAtlanta, in the county 'of Fulton and State of Georgia, have invented new and useful Improvements in 'Saws, of which the following is a specificaas the ordinary saw and almost, if not quite,

as cheap, and yet is provided with means with the assistance of which various angular cuts resorted to in carpentry may be expeditiously and easily found and marked.

With the foregoing in mind the invention will be fully understood from the following description and claims, when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a view illustrating the manner in which my novel saw is placed relative to a timber when it is desired to scribe or mark the timber for a cut of forty-five degrees. Fig. 2 is a broken side elevation of a portion of the saw on an enlarged scale.

Similar letters designate corresponding parts in both views of the drawings, referring to which A is a timber, and Bis my novel saw as a .sides of theblade at the rear end thereof.

The said saw is peculiar, however, in that it is provided with a line cl disposed at right anglesc'. a, at an angle of ninety degrees to the straight back edge bso that a handle of any style may be employed, and with a plurality of lines 6, which, like the line 03, extend from the point f, where the inner edge of the handle meets the edge Z) of the blade, to the toothed edge of the blade and are disposed at angles of fifteen degrees, twenty-two and one-halfdegrees, thirty degrees, thirty-seven and one-half degrees, forty-five degrees, fiftytwo and one-half degrees, sixty degrees, sixtyseven and one-half degrees, and seventy-five degrees, respectively, as illustrated and marked on the drawings. Each of the lines 6 is also, preferably, marked to indicate what its respective pitch adds to the foot indicated by the mark 12 inches adjacent to edge 6, or, in other words, the ratio which its rise or altitude bears per foot to a run or horizontal measurement, the seventy-five-degree line being marked 12% inches, the sixty-sevenand-one-half-degree line 13 inches, the sixty-degree line 14 inches, the fifty-twoand-one-half-degree line, 15%; inches, the forty-five-degree line 17 inches, the thirtyseven-and-bne-half-degree line 19% inches,

the thirty-degree line, 22% inches, the

twenty-two-andone-half-degree line 28% inches, and the fifteen-degree line 40% inches. This obviously renders it unnecessary for the user of the saw when he knows the span of a projected roof and the angles of the-incline to calculate the ratio which the rise or altitude bears per foot to the span. The corresponding lines at opposite sides of the middle or forty-five-degree line 0 are numbered 1, 2, 3, and 4:, correspondingly and in proper sequence as they recede from said forty-five-degree line, for a purpose presently set forth. The said lines and marks are arranged on both sides of the blade; but as the lines and marks on one side of the blade are identical with the lines and marks on the other side thereof I have deemed it unnecessary to illustrate more than one side of the blade. I also desire it understood that while I prefer to provide the blade with the lines illustrated in order that the cuts generally used in carpentry may be readily found and marked the blade may be provided with any other line or lines extending from the point f described without involving a departure from the scope of my invention.

In order to prolong the usefulness of the saw and secure accuracy in the-lines marked, I prefer to shoe the point f with metal or other suitable material, as indicated by g. The said metallic shoe g is arranged on the corner of the handle 0 adjacent to the back edge I) of the blade at and is disposed at opposite sides of the blade.

It will be appreciated from the foregoing that while my improvements considerably in crease the sphere of the tool and render it unnecessary to employ the usual square when an angular cut is to be found and marked they do not in any measure render the tool cum bersome or interfere with the ordinary use of the same as a saw. Moreover, the improvements do not add appreciably to the cost of the saw, which is an important desideratum. I have entered into a specific description of the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the said embodiment. I desire it understood, however, that such changes or modifications may be made in practice as fairly fall within the scope of my in vention as claimed without involving a departure from the scope of the invention.

Having described my invention, what I claim, and desire to secure by Letters Patent,

*1. A device for the purpose described comprisinga blade having a straight back edge, a

handle connected to the blade and having a portion disposed at one side of the blade and provided with an edge arranged flush with the straight back edge of the blade and an edge disposed at right angles to said straight back edge, whereby a point is formed coincident with the straight back edge, and lines, on the blade, diverging from the said point and arranged to serve in connection with the straight back edge to assist in the finding and marking of an angular cut on a board or the like.

2. Adevice for the purpose described comprising a blade havinga straight back edge, a handle connected to the blade and having a portion disposed at one side of the blade and provided with an edge arranged flush with the straight back edge of the blade and an edge disposed at right angles to said straight back edge, whereby a point is formed coincident with the straight back edge, a shoe carried by the handle and arranged over the point, and lines, on the blade, diverging from the said point and arranged to serve in connection with the straight back edge to assist in the finding and marking of an angular cut on a board or the like.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
